Researchers at the California Academy of Sciences and their colleagues from the University of the Philippines and the National Museum of the Philippines conducted a 42-day expedition this past spring to survey Luzon Island, the largest island in the Philippine archipelago, as well as its surrounding waters. The results were huge: They discovered more than 300 new species, from colorful sea slugs (shown here: aeolid nudibranch, or sea slug) to deep-sea armored corals and inflatable sharks. See for yourself!

A new species of Phyllidia nudibranch (also known as a sea slug) that was discovered during the California Academy of Sciences' 2011 Philippine Biodiversity Expedition. These brightly colored mollusks don't need shells for protection — instead they produce powerful toxins to keep potential predators at bay.

Pink Coral

A remarkably tall (up to a half meter), tree-like soft coral seen only in the deeper waters of a few dive sites in the Philippines. This animal is an unidentified and likely new species of the genus Umbeliulifera. At night, all parts of the animal are fully extended for feeding on plankton.

Got Wood?
